Shure Tech Tip: A Small Slice of Ohm's Law

The sound system designer required the power consumed (in watts) from each Shure product in the design. This information was required to satisfy the local electrical inspector that the sound system would not overload the electrical circuits in the vintage building. In most cases, the watts rating can be found on the Shure User Guide for the product. If it is not listed, it can be calculated; all that is required is simple multiplication. First, here is a lesson in basic electronics using water as the analogy:
